The RK05 bootup was in fact on an 11/03, not the 11/05. And it was on a door :). That machine had an RK05 and an RX01 IIRC. Had a VT52 as a console. (Everyone else on the list I'm sure cares gobs about this :) On Tue, Mar 15, 2022 at 1:07 PM Dave McGuire via vcf-midatlantic <vcf-midatlantic@lists.vcfed.org> wrote:

Hahhahahah. FUNNY BIT HERE.
check this out. someone sent me these because they just had them lying around
They're literally decoration on my wall. They're 11/03's. What are the chances of these working? :)

Wow, very early-rev 11/03s. The RAM on those boards might have issues, in particular. But you should be able to get to ODT at least.
Here's the other problem. The console on the /73 is on the mainboard. I have a pair of DLV11J's I could use - same pinning, but I'd need to identify the console somehow. Hmmmmm. (googles a bit) Ahhh, the DLV11J can be jumpered to say I AM THE CONSOLE.

Yup, that's probably the most common configuration for a DLV11-J.
I think I've found my project for tonight.
Yes. :)
Dave, thanks for the info on the 11/03 - I was almost sure the Qbus CPUs were all switchable, but thanks for the validation.
Well I've never run an 11/03 CPU in a BA23 myself, but I see no reason why it wouldn't work. I remember something about the run signal being in the right place, but that'd just affect the run LED on the front panel.
For some reason I was lumping in an 11/05 which didn't make any sense whatsoever. And yeah, that machine Im' probably went to some poor slob who I'm sure never did anything with it.
Damn. :-(
We never got it past like instruction 8 in the bootstrap.
I could've sworn that you and (who was it?) had it booting RT-11 from an RK05 at your old place in New Hope, spread out on a big door being used as a table I think.
